Solid State Drive (SSD) have made it big and have made their way
not only in desktop computing but also in mission-critical
servers. SSDs have proved to be a break-through in IO performance
and leave HDD far far behind in terms of Random IO performance.
Random IO is what most of the database administrators would be
concerned about as that is 90% of the IO pattern visible on
database servers like MySQL. I have found Intel 520-series and
Intel 910-series to be quite popular and they do give very good
numbers in terms of Random IOPS. However, its not just
performance that you should be concerned about, failure
predictions and health gauges are also very important, as loss of
data is a big NO-NO. There is a great deal of misconception about
the endurance level of SSD, as its mostly compared to rotating
disks even when measuring endurance levels, however, there is a
big difference in how both SSD and HDD work, and that has a
direct impact on the endurance …
